Overview
The B82726S2243A020 is a current-compensated ring core double choke from the EPCOS B82726 series, designed for power line filtering. It features an inductance of 750 µH at 100 kHz and supports a maximum current rating of 24 A. The component has a typical DC resistance of 3.2 mOhm and operates within a temperature range of -40°C to +125°C. Rated for 250 V AC, it utilizes a vertical through-hole mounting style with radial leads spaced 19.5 mm apart. The ferrite core construction ensures effective common-mode noise suppression for industrial applications.
Feature Summary
- Current-compensated design for differential mode signal integrity
- Ferrite ring core construction for high saturation performance
- Vertical through-hole mounting for robust mechanical stability
Applications
- Industrial power supply input filtering
- Motor drive EMC suppression
- Uninterruptible power system (UPS) line conditioning
Procurement Notes
Verify the specific suffix code against official TDK/EPCOS documentation to confirm exact electrical tolerances and lead plating specifications. Ensure the procurement channel provides original manufacturer traceability. Cross-reference the part number with the latest datasheet revision to confirm compliance with current RoHS and REACH regulations before finalizing orders.
Selection Notes
Select this component when high current handling up to 24 A is required alongside moderate inductance for power line applications. The vertical package facilitates easy integration into standard PCB layouts or chassis-mounted filters. Consider the thermal operating range and DC resistance limits to ensure compatibility with the specific power stage efficiency requirements.
Part Context
This component belongs to the B82726S series of current-compensated ring core chokes manufactured by EPCOS (TDK). These devices are engineered for robust electromagnetic interference suppression in demanding environments. The series offers various inductance values tailored for different power levels, maintaining consistent physical dimensions for modular design flexibility across product lines.
Replacement Considerations
Direct substitutes include other B82726 series variants with matching 750 µH inductance and 24 A current ratings, such as B82726S2243A020 equivalents from authorized distributors. Verify pinout compatibility and core material specifications before substitution.
